A carbon footprint (CF) analysis is the sum of the
estimated carbon dioxide and other greenhouse gas
(GHG) emissions associated with a particular activity
or industry. Without a standardized protocol for
developing a CF of water production, U.S. utilities
must draw on the experiences of other nations and
adapt approaches used in other industries.
In the United Kingdom, mandatory regulation of
emissions for large industry has spurred collaborative
development of CF methods for the water industry.
British and Australian utilities are conducting CF
analyses and using this information to better
understand the environmental impact of their water
production.
First, various utility activities are defined, information
about power and potential GHG emissions is
gathered, and the GHGs are converted to carbon dioxide
equivalents to create a CF assessment. The utility
can then use this baseline CF as a management tool to
guide decisions about sustainable operations and construction
projects as well as future resources and treatment
and transmission facilities. Includes 13 references, table, figure.
